context-layer-dreamingSynthesizes recent organizational activity into a durable context wiki.
Context Layer Dreaming is an agent skill from PostHog/posthog-foss, published by the product's own GitHub organization. Synthesizes recent organizational activity into a durable context wiki. Use when running a nightly or incremental context-layer dream, or when updating sourced organizational context from completed work.
Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: PostHog FOSS is a read-only mirror of PostHog, with all proprietary code removed. NOTE: This repo is synced automatically from the main PostHog repo. Please raise any issues and… The licence is MIT.
7 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 2c48221. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
gitFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context Layer Dreaming loads about 1.5k tokens when it runs. Until then it costs about 57 tokens; SKILL.md has 835 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

AGENTS.md, index.md, and the last ten merge commits with git log --merges --format='%s%n%b' -10. The server owns AGENTS.md, CLAUDE.md, every index.md, and scripts/; never edit, delete, move, or replace them. Do not change the wiki's tooling to make a proposed edit pass.channel-list, exclude the personal #me channel, and match every public channel id against the frontmatter of projects/<project-id>/spaces/*.md. The server scaffolds every public Space and regenerates its indexes before the dream starts. Read every matched page. If a page is unexpectedly missing, record wiki-miss: missing scaffold for <channel_id> in the run summary and leave structure repair to the server; do not create, move, or rename Space pages. On a first or seed dream, include every public Space page with no substantive content in the activity scan and inspect qualifying activity attributable to its channel. Populate an empty Space only when activity in the seed window passes the admission test; leave genuinely inactive Spaces untouched. Continue in priority order with completed tasks and their outcomes, merged pull requests, completed loop runs and summaries, and newly created event and property definitions. Use the recovery cutoff for completed tasks and their outcomes so a task that was still in progress during an earlier dream is reconsidered after completion, and the incremental cutoff for the other sources. A queued, running, test, demo, fixture, or abandoned task is not evidence of an organizational fact or decision. Inspect at most 100 newest activity items across all channel-scoped sources for each Space, and at most 100 newest items from each organization-wide source. Page through a source while it returns a next or next_cursor; for offset pagination, advance offset by the number of results returned. Stop when the applicable item budget is reached, the source is exhausted, or the oldest item is before the applicable cutoff. When a budget prevents covering the full window, record the oldest covered item, unreviewed source, and remaining cursor in the run summary. When a source is unavailable or a query fails, record that limitation in the run summary; do not treat it as evidence that the source contains no candidate facts.wiki-miss: — these lines set the health check's priorities and identify server-owned map changes for a later product update.sources, set review_after for claims that will age, condense superseded text, and use **Disagreement:** for unresolved conflicts.org/, areas/, decisions/, and existing projects/<project-id>/spaces/ pages. Run scripts/lint; fix content errors without editing the linter, publisher, generated indexes, or repository instructions. Then run scripts/lint --report for the consolidation queue./tmp/dream-summary.md, including the reason for each deletion, and run scripts/publish --dream /tmp/dream-summary.md. The publisher creates the dated dream branch, commits the wiki edits locally, and sends the bundle to the context layer API. GitHub signed-commit tools cannot commit this local bundle repository. Report publication as successful only when the publisher returns publish: landed; publish: no changes means no changes were needed. A nonzero exit means publication failed: fix the reported error or state that the dream was not published.AGENTS.md, CLAUDE.md, index.md, any nested index.md, or anything in scripts/.

Synthesizes recent organizational activity into a durable context wiki. Context Layer Dreaming is an agent skill from PostHog/posthog-foss, published by the product's own GitHub organization. Synthesizes recent organizational activity into a durable context wiki.
Context Layer Dreaming fits situations like: running a nightly; incremental context-layer dream; updating sourced organizational context from completed work.
Run `npx skills add PostHog/posthog-foss --skill context-layer-dreaming -a claude-code`. Or copy the skill folder (products/context_layer/skills/context-layer-dreaming in PostHog/posthog-foss) into .claude/skills/context-layer-dreaming in your project. Claude Code loads it when a task matches its description.
Run `npx skills add PostHog/posthog-foss --skill context-layer-dreaming -a codex`. Or copy the skill folder (products/context_layer/skills/context-layer-dreaming in PostHog/posthog-foss) into .agents/skills/context-layer-dreaming in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add PostHog/posthog-foss --skill context-layer-dreaming -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/context-layer-dreaming, .gemini/skills/context-layer-dreaming, .github/skills/context-layer-dreaming and .opencode/skills/context-layer-dreaming in your project.
Going by SKILL.md and its folder, Context Layer Dreaming needs the command-line tools its instructions call (git).
SKILL.md contains no URLs. Its commands use git, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Context Layer Dreaming is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.5k tokens (SKILL.md is roughly 5.9k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
